Your shop, your data
Your stock, sales, customers, staff, and reports belong to your shop and are yours to export at any time.
Counter staff friendly
POS screens are designed around fast search, clear cart totals, and low training effort.
Features
Everything a retail POS needs after the first sale.
Not only a billing screen. Gray POS connects sales, stock, purchases, customer credit, reloads, repairs, cash, and reporting in one place.
Fast counter sales
Scan with a USB scanner or the phone camera, hold a bill while you serve the next customer, split one bill across cash and card, and take returns without leaving the POS screen.
Stock by branch and variation
Track every item by branch, size, and colour, run stock counts, move stock between branches, and write off damage with a manager's approval.
Purchases and suppliers
Record supplier invoices, receive stock into the right branch, note best-before dates, and pay suppliers in full or in parts.
Customer credit and payments
Sell on credit up to a limit, settle the oldest bills first, give store credit on returns, and keep cash, card, bank transfer, and PayHere references clear.
Ready for grocery counters
Sell rice and vegetables by the kilo, read the weight from a scale on the till or scan the stickers it prints, keep a credit book, and see which stock expires first.
Mobile reloads and services
Sell Dialog, Mobitel, and other reloads from the till, keep each reload SIM's balance, dial the USSD code in one tap, and let customers request a reload on a counter tablet.
Repair workshop
Take in a device with the customer's problem, move it through each repair stage, use parts from stock, charge labour, and print the job card and warranty.
IMEI and serial numbers
Record each phone's IMEI or serial number when it arrives, sell that exact unit, and print it on the bill with its warranty.
Cash register shifts
Start each shift with an opening float, record cash in, cash out, and expenses, count the drawer at closing, and see any shortage for review.
Bills and screens in your language
Staff use the system in English, Sinhala, or Tamil. Bills print as thermal receipts or A4 invoices in your shop's language, or go to the customer on WhatsApp.
Staff roles and approvals
Give each person the right role - owner, manager, or cashier - have large discounts and stock write-offs approved, and keep a to-do list for every branch.
Reports for owner decisions
See sales, gross profit, taxes, stock movement, low stock, and branch performance in your own shop currency.
